The die-casting process is a high-efficiency, non-cutting metal forming process, from the early nineteenth century with lead-tin alloy die-casting press the word has been 150 years of history. As the die-casting process in the modern industry for the production of metal parts with unique technical characteristics and significant economic benefits, so a long time people around the die-casting process, die-casting molds and die-casting machine for a wide range of research and achieved gratifying results.

The future development trend of die-casting is: die-casting process to adopt new technology to improve the quality of die casting, expand the scope of application; die-casting machine to achieve serialization, large-scale and automation; die-casting mold to improve service life. In short, for the die-casting production to open up a broader prospect.

The principle of die-casting process is the use of high-pressure metal liquid into a high-speed metal mold cavity, the metal liquid under the pressure of cooling and solidification and the formation of castings. Cold and hot chamber die casting is the two basic ways of die casting. The molten metal in the cold chamber is poured into the press chamber by manual or automatic pouring device, and then the plunger is advanced, and the molten metal is pressed into the cavity. In the hot chamber die casting process, the chamber is perpendicular to the crucible, and the molten metal flows into the press chamber through the feed inlet on the chamber. The plunger moves down to push the molten metal through the gooseneck into the cavity. After the molten metal is solidified, the die-casting mold is opened and the casting is removed to complete a die-casting cycle.
